Keep spending! Why Chelsea will need more than Diego Costa up top to light up the Premier League

It’s no longer a matter of if but when Diego Costa is announced as Chelsea’s latest signing and fans will be hoping he builds on his prolific 2013-14 campaign with Atletico Madrid.

The Brazilian born forward netted over 30 goals for the La Liga winners and Champions League finalists Atletico over the last campaign but did not exactly receive glowing reviews for his performances at the World Cup for Spain.

Now, it would be unfair to judge the 25-year-old on his performances in Brazil as there are several high profile players currently enduring a shocker at the finals, but it’s enough to raise a few questions and Chelsea are making a risk by investing so much in him.

It would appear that the pressure is already heaping up on him even before he has been officially confirmed so it’s important that Jose Mourinho and Chelsea don’t pin their hopes on or put too much a burden on Costa’s shoulders. He’s only started to kick on over the last two season and it may take him time to adapt to England and Chelsea’s style – especially if the football is to be more expansive than it was over the last season.

No player is a guaranteed success and I believe Costa will prove himself as a good signing but he can’t be all Chelsea have. Mourinho doesn’t want to be Vicente del Bosque and look to his bench when things aren’t happening for Costa only for his eyes to fall upon Fernando Torres. The Blues need to make sure they give themselves options next season and the more competition for places the better.

Mario Mandzukic has been mooted as a potential target but the rate in which Bayern Munich created chances last season made him look much better than he is. Edinson Cavani’s name always pops up but Paris Saint-Germain will want more than they paid and are unlikely to get it. It’s unlikely that Romelu Lukaku will be given the chance that he deserves so Chelsea may have to think outside the box on this one.
